This is a bit of a missed item, but Rick Brannon on his other blog, Pastroal Epistles, has started a series on the use of the Pastoral Epistles by the Apostolic Fathers. Here is his introduction, followed by the Epistle to Diognetus, parts one, two, three and four .

Mark Gordon on The Suicide of the West blog features Justin Martyr and on the Nicene Creed in his 40 Days, 40 Graces reflection on the "practices, doctrines, personalities, and moments that have been particularly precious to me during my ten years as a Catholic.". Both of these are late, but thanks to Mike Aquilina for directing me to it.
